Angle Seat Piston Valve

Angle Seat Piston Globe Valve - Y Pattern

Angle seat piston globe valves or Y pattern globe valves are best suited for most applications if manufactured from Stainless Steel as this is a strong chemical and wear resistant material especially when combined with PTFE sealing. Some better manufacturers use a stainless pneumatic air actuator (pneumatic head) which prevent heat, wear and maintenance damage and vastly increases the valve service life.

The combination of correctly chosen materials of construction has generated one of the best quality compact high performance reliable pneumatically operated angle seat piston globe valves in the market today, avoiding the pitfalls cheap Plastic actuators or bronze bodied valves these more robust series all stainless valves outperform outlast and yet still remain highly competitive fluid or gaseous media control solution in the market today.

Typically all Angle Seat Piston Valves will have Anti-Water Hammer Design when flow is from under the seat and the better ones will have self-cleaning valve seats, higher Kv flow values and pressure ratings.

Continued focus on quality and reliability through volume / stock purchasing as offset most of the additional costs for an all stainless steel angle seat piston valve design making these valves a cost effective solution even for general purpose water and high cycle aggressive or corrosive, glutinous, chemical or steam application.

The seat is set at an angle to provide the maximum possible flow when unseated. Angle seat piston valves are particularly suited to applications where high temperatures, large flow rates, aggressive and viscous media are required, such as steam, water, heavy oil and Acids or Alkali’s . When used in reverse the angle seat piston valve will eliminate water hammer when operated.
